The Lowdown
Alright, Rusty here. Let’s talk about what’s shaping up at Costeño Beach over the next couple of weeks.
To be straight with you, the first week is pretty average. We’ve got a bit of swell hanging around but the conditions are mostly ordinary. Starting Saturday the 29th, it’s cross-on with a short-period 5ft NE swell and combined energy sitting at 214 (moderate). The water’s sitting at a warm 84°, which is normal for this time of year. Sunday the 30th doesn’t look much better, still cross-on and marginal. Monday the 31st afternoon goes glassy with a small 3ft NE swell and energy dropping to 81 (weak). That’s about as good as it gets in the first few days, but it’s nothing to write home about.
From Tuesday September 1st through to Thursday the 3rd, we see glassy conditions pop up on a few afternoons but the swell stays small and weak—around 3ft to 4ft. There’s a hint of clean surf on Wednesday afternoon the 2nd with a cross-off wind, but the energy’s low at 73 (weak). Honestly, it’s surfable but very ordinary.
The real standout window arrives Monday September 7th. Monday morning we’ve got 4ft NE swell with a period bumping up to 8 seconds, combined energy at 224 (moderate), and glassy conditions. That’s clean, lined-up surf. Monday afternoon stays glassy with 4ft and period up to 9 seconds—this is groundswell starting to push in and it’ll be well-shaped at the beach break if you pick your peak. The week only gets better.
Tuesday September 8th is the clear highlight. Tuesday afternoon you’re looking at 7ft NE swell, period 8 seconds, and a combined energy of 579 (strong). Glassy conditions. That’s solid, powerful surf. A bit much for beginners—over 5ft—but for intermediates and up, this is the best session of the whole forecast. Wednesday the 9th afternoon goes calm and glassy with a 7ft NE swell (468 energy, strong). Thursday the 10th afternoon sees 7ft NE swell with energy hitting 650 (strong to very strong), again glassy. That Thursday is a standout too—clean, punchy, and consistent.
Into Friday the 11th, still glassy with 7ft NE swell (574 energy). Saturday the 12th afternoon goes glassy with 7ft NE and 528 energy. That whole stretch from Monday the 7th through Saturday the 12th is the best on offer. After that, Sunday the 13th turns cross-on and choppy with a 9 mph wind and energy dropping off—so get it while it’s good.
Crowds? Costeño Beach can get busy sometimes, especially when the surf turns on like this. Keep that in mind.
Expect clean, good quality surf Monday the 7th through Saturday the 12th. The standout is Tuesday the 8th and Thursday the 10th—both afternoons are glassy, strong swell, and well over 6ft. That’s expert territory by Thursday.

Information about the Costeño Beach Surf forecast
The above surf forecast table for Costeño Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Costeño Beach can be found by selecting the local surf guide option on the grey menu. Our Costeño Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Costeño Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Costeño Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
